Positive global trends for the PIM industry?
For the global PIM industry, 2018 appears to have been a year of positive growth. With a lack of hard data, however, the true picture of progress in MIM and CIM is becoming increasingly hard to come by. In both Europe and North America the industry has, to a large extent, relied on annual surveys of sentiment; whilst such surveys give some degree of insight, the complete picture is compromised by limited participation and a lack of raw data. Although regional trade associations would jump at the chance to assess full production data from part makers and materials suppliers, the reality is that within the competitive environment of PIM, this is now almost impossible to achieve. What we are left with is a fragmented view of trends in the PIM industry, sometimes with heavily contrasting estimates of sales values, tonnages, growth and the outlook for the industry. As a result, the performances of powder, feedstock and equipment suppliers have for some time been used as a barometer for the health of the industry. Now, however, with the rapid growth of metal AM, even these indicators can lead to confusion. MIM furnace makers and powder suppliers are busy and are looking to invest in increased capacity, but to what extent will this be driven by MIM-like metal AM processes, rather than growth in MIM itself? Japan is, of course, the exception, and the latest data, published on page 8 of this issue, shows growth in 2017 and a forecast that this will continue in the near future.

In this issue57 Threat or opportunity? The MIM
industry as a partner, a target and a market for metal AM
In September, HP announced its entry into the world of metal Additive Manufacturing with the launch of a new binder-based AM system, the HP Metal Jet. The fact that HPs launch partners, Parmatech and GKN Powder Metallurgy, are well-known MIM producers serves to highlight just how close the worlds of AM and MIM have become; a fact evidenced by multiple launches and developments over the past few years. In this report, Nick Williams reviews the attraction of AM for MIM producers, and the equally strong attraction of MIM for AM machine builders.
67 WORLDPM2018: Global MIM markets show healthy growth
The WORLDPM2018 Congress & Exhibition, Beijing, China, highlighted not only the rapid industrial growth that has been achieved in the country over the past two decades, but also the many advances made in PM materials and production technology. This applies equally to Metal Injection Moulding, which has been enjoying high growth in China as well as in other regions around the world. Bernard Williams summarises the global status of MIM as well as production and technology trends based on key presentations during WORLDPM2018s Plenary and Special Interest Sessions.
77 Ceramic Injection Moulding and Ceramic Additive Manufacturing side by side: Opportunities and challenges
The arrival of production-ready MIM-like metal AM technologies is today opening up a new world of opportunities for MIM producers. As Tassilo Moritz and colleagues from the Fraunhofer Institute for Ceramic Technologies and Systems (IKTS) explain, the same opportunities will soon also be open to CIM producers. In this article, two ceramic AM processes, both based on CIM-like thermoplastic feedstocks, are reviewed and the opportunities and challenges of the processes exam-ined.
87 Euro PM2018: Innovations in MIM highlighted
in Bilbao A number of technical papers presented at Euro
PM2018, Bilbao, Spain, October 14-18, 2018, addressed processing and compositional developments in Metal Injection Moulding. In this report, Dr David Whittaker reviews four papers that cover Lost-Form PIM, an innovative debinding and sintering process, the MIM of Ti-6Al-4V HDH powder with the addition of yttrium, and the use of iron as a low-cost sintering aid for Ti-6Al-7Nb.
